Abstract

La présente invention concerne un contrôleur numérique (408, 412, 416) destiné à commander le fonctionnement d'un convertisseur à commutation DC-DC. Un système de commande de retour d'informations numérique permet de recevoir une tension d'entrée analogique (406) représentant la sortie du convertisseur à commutation et traitant de façon numérique la tension d'entrée analogique par comparaison de celle-ci à une tension de référence puis, déterminant des signaux d'attaque analogiques permettant de commander le fonctionnement du convertisseur à commutation (402) de façon à fournir une sortie régulée. Le système de commande de retour d'information numérique (408, 412, 416) fonctionne conformément à des éléments paramétriques d'exploitation prédéterminés. Le système de commande de retour d'informations numérique (408, 412, 416) possède aussi des entrées de surveillance et des entrées de commande. Un microcontrôleur (442) surveille le fonctionnement du système de commande de retour d'informations numérique et est capable de modifier les éléments paramétriques d'exploitation sous certaines conditions prédéterminées.
